Exceedingly heavy rain on Wednesday led to significant flooding in the Boulder, Colo. area, AccuWeather.com reports.

Rain began early Wednesday morning and continued throughout the day, becoming heavy in the evening, when it dumped as much as 1 inch of rain per hour.

The torrential downpours brought somewhere between 5-10 inches of rain across the area. Excess flooding broke the Pinewood Springs Dam, sending rushing water into the city of Lyons.

At least one person was killed in a collapsed home due to the flooding.

Another life was taken on the 200 block of Linden in Boulder, according to the Boulder Office of Emergency Management.

Highway 66 was under water driving into Lyons, and Highway 7 was also shut down.

Roadways were reported as impassable in the city of Boulder's Office of Emergency Management.

Colorado University's Boulder Campus closed for Thursday and Friday "due to effects of severe flooding and the ongoing weather emergency," according to the school's website.

Boulder's Emergency Management spokeswoman Gabrielle Boerkircher told the Associated Press that about 400 students were evacuated.

Water was reported in dormitories and underpasses on campus.

Boulder Valley School District also closed school Thursday.

Emergency managers reported multiple home collapses in the Jamestown area. Due to the flooding and mudslides, multiple roads were cut off.

The city of Boulder's emergency management office reported that rescue teams were ready to go, armed with seven three-person vehicles, able to go through deep water, whenever conditions become safe and possible to enter.

The office also reports that search and rescue helicopters are ready and on standby, waiting until conditions become more stable.
